摘 要:
分析了電話機(jī)外殼下蓋的塑件工藝特點(diǎn)。介紹了電話機(jī)外殼下蓋注射成型結(jié)構(gòu)及模具的工作過程和電話機(jī)外殼下蓋注射模具結(jié)構(gòu)的設(shè)計(jì)方法。分析了模芯零件的選材、熱處理、下蓋的塑件的機(jī)構(gòu)要素，塑件的尺寸公差和精度選擇。此電話機(jī)外殼注射設(shè)計(jì)特點(diǎn)是：點(diǎn)澆口形式的雙分型面的注射模,采用斜桿導(dǎo)滑的斜滑塊分型抽芯機(jī)構(gòu)。

Abstract
Analyzed under the telephone outer covering to cover models the craft characteristic. Introduced under the telephone outer covering covers the injection to take shape the structure and the mold work process and under the telephone outer covering covers the injection mold structure the design method. Analyzed the mold core components selection, the heat treatment, under has covered models the organization essential factor, modelled the size common difference and the precision choice. This telephone outer covering injection design characteristic is: Runner form duplex profile injection mold,Uses the strut to lead the slippery slanting slide minute to pull out the core organization.
Keywords : Under the telephone outer covering covers; Slide; Injects the mold
